TO ALL WHOM IT MAY CONCERN:

Be it known that we,EMEaYT..WHnnLnn and'WILLIAM H. VAUGHAN, of Cannelton, in the county of Perry,- and State of Indiana, have invented a new and useful Improvement in Machine for Sawing Laths, &c.; and we do hereby declare that the following is, a full, clear, and exact description thereof, which will enable those skilled in the art to make anduse the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side sectional elevation of an improved lath and strip-sawing machine, taken in the line z x, fig. 2. I

Figure 2 represents a plan. Figure 3 represents a partial end elevation. Figure 4 represents a similar view of opposite end. .Figure 5 represents a detached side view of a clutch-wheel, with spring attached. Similar letters of reference indicatecorresponding parts. i This invention relates to anew and improved machine for sawing laths, pickets, and strips for wheel-spokes, chair-stuff; &c., directly from the circumference of a log, without waste;- and the improvement consists in placing upon a reciprocating carriage vertical and horizontal circular saws, which work in concert, and out together at the same time a lath or strip from the sideof a rotating log, suspended on a feed-rest, made adjustable to a log of any/length and size, all operated by machinery automatically, as hereinafter particularly described.

A is the bed-frame. B is the reciprocating carriage, on which are hung the horizontal circular saw a and the verticalsaw b, which take motion by a continuousband, c c, passing over pulleys d d on the saw-shafts, from the pulley e, on the driving-shaft g, actuated by pulley h, and also passing over a counter-pulley,-h, at the I opposite end ofthe hed-frame. The carriageB-is moved back and forth on a rack, It, by a'pinion, m, on a shaft, m, that takes motioxvfrom a pulleyflt, on the shaft of the vertical sawb, by bands running over intermediate pulleys, shown clearly in fig. 2. Provision is 'made for reversingthemotion to suit the length of the cut. The saw-boxes are made adjustable, to keep the saws in line and compensate for their wear. The log 0 is supported over one side of the saws, on a rest formed ofa stationary headfp, and a sliding head, p, moving on hor,izontal bars 3 s, to adapt it to logs of various lengths. The log is hung by spindles g g, driven or screwed into the centre. of the ends, and hung in the upper. ends of sliding 'upright bars 1 7', connected with the heads pp. The upright bars are raised and lowered, to vary the width of the cut asfrequired, by adjusting-screws t t, figs. 1 and 4, which work under the feed-wheelsu u, whichbear the log and rotate it, one ofwhich, on the stationary head 21, is toothed, and the other, on the sliding head pf, is loose and smooth-faced. The log is fed to the saws by means of a belt from a pulley, n, on the driving-shaft g, which passes to a clutch-wheel or pulley, m on a vertical shaft, g, on the upper end of which is a worm, w,-that works a worm-wheel, w, on the shaft 'oi' the toot-lied feed-wheel u. The clutch-pulley 11. is thrown in andout of gear by an arm, 1), moved forward by a pin in the sideof a gauge-wheel, g, which is propelled by teeth in the clutch-pulley. The gauge-ratchet wheely is.

held stationary bya pawl, .2, until the pawl is raised by-a'double incline, 2', on a horizontal sliding rod, Z, having fingers ff, which are struck by a pip in the sideof the reciprocating carriage B, at both ends ofits traverse, to raise the pawl z, and release it from the gauge-wheel y. The gauge-wheel is thrown back by a spring, fig. 5, and a movable pin is also provided, to be set a t any point inthe gauge-wheel, for tripping the arm under the clutch-pulley, and'letting it-drop into gear. The worm-shaft and gauge-wheel then both begin to revolve, and the pin being moved, allows the clutch-wheel to turn only a given number of times before the other pin brings the arm 11 up, and throws the clutch-wheel out of gear again. Thisinovement regulates the'thlck-ness of the stufi' sawed. The finger is made adjustable on the sliding rod Z,'and fastened by a set-screw, for the purpose of plucingit to strike the pin on the carriage at any given point, adapted to long or short legs. I

It will be observed that the machine cuts as well with the back as the forward motion of the carriage, th s saivs striking either end of the log alike, and thus making no loss of 'motion.

Having described our invention, we claim as new, and desire to secure by Letters Patent-- 1. The adjustable rests pp, in which are mounted feed-wheels u u, in combination with the sliding sup porting rods 1 r and bars 3,1111 constructed, arranged, and operating substantially as and for the purpose herein shown and described.

2. The'carriage B, on which the vertical saw 6 and horizohtal saw a are mounted, when arranged to be moved on ways A A, by means of a tack and pinion, and when arranged to operate a. rod, Z, through the medium of a pin, f, on the some, substantially as and for the purpose described.

3. I claim the rod Z, provided with pins ff and double incline i, when arranged to be operated from carriage B, in combination with the pawl-z and gange-rat chet wheel y, constructed, arranged, and operating substantially as and for the-purposes set forth.

4. I claim the toothed feed-wheel u, to which motion is given by wortn w, on shaft g','throngh the medium of clutch-pulley 17?, on same shaft, substantially as described.

5. lclaim the combination of the clutch-pnlley n arm 21, gauge-ratchet wheel y, and shaft 9', all constructed alnd arranged substantially as described.
